This invention relates; on improvement in. fountain pens, Wherei 1 pr Wit-1WD 1%; ma lo for utilizing substantially the entire horrel ot the pen are an i k reservoir; means being); 5 provided \vherehy the pen inny he rendil land conveniently till-ed. with ink.

The pen barrel at the shoulder formed by the reduced portion is torn'ied with an opening); 10, I orinally sealed. when the cap in cloi-sod po ition. and open when the up has been 'ven app-regimetely a, halt turn. The extended stem 7 of the valve hears heinrath the ezip 9, the relation being; such that when the cap in in closed pm; the valve will he held to close the opening l in the lower ahut went 3, While when the cap is in open position, the valve tree to move in the HD1100 hetween the ehntinen A l l hon it is desired to fill the pen. the pen end thereotl .ie ineerted in a body of ink atter the cap hoe been moved to inoperative or open poeitioi'i, the cap 9 {given :1. partial rotation. to open the ventlh and relieve pressure on the ve he 5. Suction is then applied to the upper end ot the barrel, as "for exinnp e hy the month of the N561. and ink drawn into the barrel troni the pen end. lin this operation it has been tound that the air may hi nullieiently exhausted from the in rrol to permit the ZItJIIOSPllOl-lh pressure on the ourtl aco ot the ink in the conhiinor to force the ink up into the barrel. 'llhie: air Withdrawal is not nutlielent in vohnne or prieenre to lift the cilve 5 to close the opening 4 in the upper aontn'ient E2, hencethe iik Will continue to flow into the he rel until the upper level thereof roojhee the "alve and floats the some against the lower end (it the opening 4t of the ahutinent 52.. eealingg' the oi'x-eningr alrains-it the paeean'e oi int: and insuring that no ink can pose the valve and hence reach the mouth ot the uner. Notivithetandiing repeated 0X- periniente, the olive has been Found. to tunetion in every inetai'ice exactly 21R denrrilmd, this operation depending upon the play pern'iitted the valve hetween the allotments. It the space here is correct, air may be freely Withdrawn from the barrel without perniitting the ink to pass the valve.

After the barrel has been filled, the cap in turned to closed position, sealing the vent l0 and at the some time forcing the "alve to clone the upper end of the opening" l in the lower allotment 3 to prevent any ink from rmiohing ahove the alnitini-in t in the tilting); of the pen or the like.

The important tootnre of the pen deserihed is the fact that without material change in the conventional sine, suhetantiolly double the usual ink capacity is provided. Furthermore, the pen readily lends itself to o thorough rimming, as water or other cleansing CID fluid may be drawn into and ejected from the barrel by suction. and pressure through the agency of the mouth and lungs, thoroughly cleansing all partsr The operation in lilling and using the pen is 01" the utmost simplicity, there being no parts to get out of order, and beyond obvious manipulation of the cap 9, no particular attention is required to secure the desired results. The simplicity and few parts of the pen commend it lrom a --mercial aspect, particularly when such are inseparable from the pen and require no adjustment or manipulation on the part 01" the user to secure the desired results. The ink will feed readily from the pen, it being understood that the opening 15 is of apnropriate size to take 'are of the flow, though if desired, in the event of stoppage ot the flow through a thickening of the fluid or an extremely small quantity thereof in the barrel, the cap 9 may be turned to admit air through the vent 10 and immediately thereafter closed, permitting ink delivery by gravity restricted by the size of the opening leading to the pen point.

'lhL material of the various parts other than that of the valve 5 may be the conventional mate-rial employed in constructing tonnta-in pens, though obviously it may well be that the parts can, within the invention, be constructed of other material, for example the barrel an d other parts may be constructed of transparent or semitransparent material to visibly indicate the quantity of ink in the barrehand additionally provide a more attractive implement. The material, so long as it permits the function desired. is of no particular importance so far as the invention is concerned and any and all kinds of appropriate material is contemplated for use.

' It is of course to be understood that the fountain pen contemplates the use of the usual pen point, but 1 consider it as within the spirit of the present invention as adapting the improved fountain pen. for use with a I pen point constructed of any desirable material other than that now employed; that is to say, the pen point may be constructed of the present material or any other material now known or hereafter known and s(- rviceable for use as a pen point.

The arrangement of pen described lends itself adn'iirably to the application thereto or a fixed pen clip such being secured, s illustrated in the drawing, in the barrel. In this position, the pen clip is on the upper side of the barrel when using the pen, entirely out of the way 01 the lingers, and forms no obstruction, being thus ready to serve as a clip when desired and remaining a permanent part ot the construction.

hat I claim to be new is:

In a fountain pen, a barrel adapted to serve as a reservoir for ink, screw threads formed on the upper'part of the barrel, the section having the threads having a vent therein, a cap adapted to be threaded on the barrel and seating on a shoulder formed thereon, the said cap closing the vent opening, parallel abutments formed in the barrel adjacent the top, the said abutmcnts being only slightly spaced from each other, and having a central opening through both of said abutments, a disk alve operating between the said abutuicnts and adapted to be seated on either of them, a valve stem passing through the said disk valve and extending through both openings, the upper end of the valve stem being engaged by the cap when in turned down position.

In testimony whereof I affix my signature.
